HYGlENIc vBEER-PRl-:ssuRE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 657,498, dated Septemberl, 1900. Application filed November 15, 1899. Serial No. 737.117. (No model.)

To all whom it may concern:

Be it known that I, CHARLES PETERS, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Hygienic Beer- Pressure Apparatus, of which the following is a full, clear, and exact description.

The invention relates to apparatus for forcing beer or other liquid by means of compressed air` from a keg or barrel ina cellar to a dispensing-faucet located at a bar. y,

The object of the invention is to providea new and improved hygienic beer-pressure arranged to cool and purify the air previously to passing it into a barrel or keg, to keep the beer in a natural condition, and to prevent raising its temperature-by the ,com-

pressed air, the beer in its passage from the barrel or key to the faucet being cooled to the desired degree, so that the .beer inally drawn is in a perfect condition.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodimentof my invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectionalside elevation of the improvement. Fig. 2 is an enlarged longi tudinal section of the air-reservoir andthe automatic air-outlet valve. Fig. 3 is a transverse section of the improvement on the line 3 3 in Fig. l. side elevation of the beer-cooler and the'supplementary air-cooler. Fig. 5 is a transverse section of the same on the line 5 5 in'Fig. 4. Fig. 6 is an enlarged sectional side elevation of the automatic air-outlet valve in the airreservoir and in an open position. Fig. 7 is a similar view of the same in a closed position; and Fig. .8 is an enlarged sectional side' elevation ofthe air-inlet valve at the barrel or keg.

A-chamber A, having double walls, is built in a cellar and is of any suitable size` and is 4adapted to contain the barrels or kegs B from which the beer is to be drawn at faucets C on Fig. Liis an enlarged sectional the pump is set in motion cold air is drawn from the ice-box Dinto the pump F by way ofthe pipe E. As shown in Fig. 1, the pump F is a hydraulic pump and is conby a pipe F2 with a water-discharge, and said F3, opening into an air-reservoir G, suitably supported in the chamber A. Now it is evident that the cold air drawn into the pump F is compressed by the latter and forced into the reservoir G, from which the air passes by an outlet-pipe H into a supplementary cooling-box I to connect with a pipe J, extending longitudinally in said box I and containing a reducing-core J' to cause the incoming air to travel in a thin stratum through the pipe J, near the wall thereof, as will be readily understood by reference to Figs. 4 and 5. The pipe H opens into the pipe J, at one end thereof, and the other end of said pipe is connected by a branch pipe J 2 with a pipe J 3, similar to the pipe J and likewise containing a reducing-core J4. From the pipe J 3 lead a number of pipes K to connect with barrels or kegs from which beer is to be drawn `to corresponding faucets C at the bar. Each of the pipes K is provided with a valve and connects with a device L for purifying ain-such, for instance, as is shown in the'Letters Patent of the United ary l2, 1895. A discharge-pipe N leads from theA purifying device L to connect by a Valve O with a bung P, driven into the barrel B to tap the same, the bung containing the usual pipe P, extending to near the bottom of the barrel or keg and connecting `by a suitable p coupling at its outer end with a pipe Q, leading to the corresponding faucet C. A porpump is also provided with an air-outlet pipe nected by a pipe F' with a water-supply and States No. 534,241.3, granted to me on Febru- IOO f Io

As shown inLFig. 1,'the box I is arranged in thefaucets C. From the foregoing .it is evident that when the apparatusis'in use cold` andfcomparaf tively-pure air is drawn from the ice-box'D andforced by the pump Finto the reservoir Gr, from which ythe air isdrawnv by way of the pipe `H A'and subjected to a second vsupplesel mentary cooling in 'the pipes J J 3,`asprevi- 5"' ouslyfexplained, and this air before passing tothe barrel is purified in thepurifying .device L, so that absolutely pure and cold1aifr onlypasses into the keg or barrel B.. Thus the air'in the barrel `giving the desired pressure to thebeer to `force it up to the faucetsy C is not liable to raise the temperature ofthe beernor is it liable to "injure the beer, as Vit is in apure state. p g

In order to `prevent any water that may pass through the air from the hydraulic pump F from passing into the pipeH Aand lfinally 4o' into the keg, I provide an automatic valve R p Figs. 2, 6, and7.) .'Thisvalve R consistsof-a v ervoir G can' passthrough the tube R3 into `iloat R', held in a 'cage' R2, suspendedin 'the reservoir G, anden the top of the Iioat .R is a `tube R8, containing "in its bottoma dis'kjR4 for closing the lower end of 'the pipe H, whichl extends loosely into 'the .tube R3. Aslong'as. e no water is in the reservoir `Gr the iloat'R'A is seated .in the bottom of the cage-R2, andthe from the disk-valve R4, so that air-in the resi the pipe H. When Water accum ulates inthe reservoir G, it finally raises thefloat R', so'` that the disk-valvel R4 moves in contactwi'th T1 the lower fend of the pipe lH and closes the `sanne (see Fig.` 7.) to shut -off the air fromv the pipe H.

j cetk C at once ldetects thatggthefvalve isf-ina sary that the accumulated water in the .res-

"In order to prevent any-foam o'r other mat-V ter from rising 'from thehung .Pinto the `pipe The operator inl charge ofthe fau andlpurifyin'gf.device valvel is p'r'otidedg. (Shown indetail i-nFig.;8.) The '.pip'e' N, which,y is preferably dexible, connects .bylaniinlet VO' Witha port O2, adapted' toV be Vclosed by a diaphragm-valveO?, mounted in .fa chamber 104. of said Walyfe` 0, :the-chamber .fObeingconnected byea boreOwith an out-` rfletwnoz'zle O6, opening intojthebung-P. yl` As lflongas the valve O is free from foam, the air passing under jpressnre "into p the inlet j O 'presses the diaphragm. O3 into an innermost position to lallow the air to passthediaphragm to. .reach-the lbore 0.5- and nozzle O6 y and pass from. the latter through the bunginto the keg or'barrel. "vWhen, however, theffoam from fthe keg or barrel Vrisesinto the chamber O4 and .presses k,the .',diaphragml-valve` 03 to its rvseat, then the air is cutoif from the chamber O4.' Thus whenfthisftakesplace the foam is not li'ablepto get upinto thefpipe jN and `puri- .fying'deviceL and asno air passes into' the barrel or keg'fthe operator of `lthe'faucet C soon detects .that the valve O requires cleaning before the apparatus'is againfput'in serviceable condition.

. In order to allow @quick cleaning ofthe pipes-Q when theyiare,detached'frorn the y pipes P', a cleaning apparatus S is provided similar in construction :tothe one shown and L described in the LettersPatent of .theUnited f States No. 557,874 granted to meon April 7, A 1896. This apparatusis provided with alhose S', adapted to be connected with a water-supply faucet S2 or other supply,-.and is also provided with ahose S8 for connection with a faucet-C. An air-pipe F'i connects with the pipe F4, containing the pressure-gage F5 for indicating klthe air-pressure in thek reservoir G.
